[TenTec] COMMUNICATIONS SPEAKERS Article

[Rick - DJ0IP / NJ0IP]

Barry, Jim,  

I have a pair of Rat Shack Minimus-7 (label says Realistic).
I don't know if it is from the same company you guys are referring to or
not.
The audio quality not bad.  Do you guys know it?  
How does it compare to the ones you are referring to?

BTW, having two identical speakers is great for comparing two radios.
I used these when comparing my Eagle and my K3.
I even swapped them after a couple of days, just to be sure it wasn't the
speaker.
The Eagle won on audio quality; wasn't even close.

I couldn't agree more with Jim's comments.  If you want to tailor the sound,
do it in the electronics, not in the speaker.  The speaker should be an
accurate transducer.

And I love my little RCA/Radio Shack/Optimus speakers (Pro-X44AV)!
